Evaluation of 4 Different Suture Threads in A Sample of Dentistry Suture‐Naïve Students: A Randomised Controlled Trial

European Journal of Dental Education, EarlyView.
ABSTRACT Introduction Suturing is a crucial step in oral surgery, directly affecting wound healing quality. Simple interrupted suture is widely used in dentistry, often performed by novices using silk sutures due to their ease of use and low cost. However, several alternatives could also be suitable for less experienced practitioners.

Permeation Properties of Laser-Sintered Polyamide 12 Sheets in Comparison to an Extruded Polyamide 12 Film

, 2020
Laser sintering of polymers is widely used for the production of individual products and small-batch series. However, the qualification of laser-sintered polymeric components for new application fields, e.g. in the food and packaging industry, is still limited due to missing knowledge on physicochemical material properties.

Thermal Conductivity Measurements of Polyamide 12 [PDF]

, 2011
An important component in understanding the laser sintering process is knowledge of the thermal properties of the processed material. Thermal conductivity measurements of pure polyamide 12 were conducted based on transient plane source technology using a Hot Disk® TPS500 conductivity measurement device.

Oxyluminescence of polyamide 12

Polymer Degradation and Stability, 1994
Abstract The oxyluminescence of unstabilised samples of polyamide 12 was studied in the temperature range 80–250°C. The chemiluminescence intensity was first recorded at constant oxygen pressure and temperature. The kinetic curves reveal the existence of two kinetic stages.

Fusion bonding of polyamide 12

Polymer Engineering & Science, 2001
AbstractThe strength of fusion bonds between polyamide 12 plaques has been investigated as a function of processing conditions, using the double cantilever beam geometry to measure the mode I critical strain energy release rate, Gc. Bonding was carried out using an instrumented press, which allowed systematic variation of the bonding time, the holding ...

The crystallization kinetics of polyamide-12

Colloid & Polymer Science, 2001
The crystallization kinetics of polyamide-12 has been investigated using a combination of differential scanning calorimetry (DSC) and hot-stage optical microscopy. The DSC data for isothermal crystallization were consistent with a simple two-parameter Avrami model for isothermal crystallization and optical measurements of the spherulite growth rates ...

Thermoplastic Elastomer Based on Epoxidized Natural Rubber/Polyamide-12 and Co-Polyamide-12 Blends

Advanced Materials Research, 2012
Thermoplastic elastomers based on blending of epoxidized natural rubber with 30 mol% epoxide (ENR-30) with polyamide-12 (PA-12) (i.e., ENR-30/PA-12) and blending of ENR-30 with co-polyamide-12 (ENR-30/CO-PA-12) were prepared by dynamic vulcanization technique. It was found that the dynamically cured ENR-30/PA-12 blends exhibited higher tensile strength,

Relaxational properties of plasticized polyamide-12

Polymer Science U.S.S.R., 1979
The dielectric relaxation characteristics of polyamide-12 (polydodecalactam), plasticized by sulphonamides of the type RSO2NHC4H9 (where R is phenyl, β-naphthyl, 3-pyridyl or 8-quinolyl), were studied over a wide range of temperatures and frequencies (−100°C to + 100°C and 0.5–200 kHz). The glass temperature and relaxation time were determined, and the

Resin transfer moulding of anionically polymerised polyamide 12

Composites Part A: Applied Science and Manufacturing, 2005
Liquid composite moulding of Lactam 12 monomer and activating system (APLC12) into satin weave carbon fabrics is investigated, with emphasis on minimising the void content in the final part. The main sources for void formation are identified. The solidification shrinkage is quantified to account for at most 9% in the matrix. Optimal flow conditions are
